ROBBIN- npp'lioation filed November The present invention relates to an improvement in bobbins; A Theobject of the invention is to improve the construction of bobbins to render them more durable and satisfactory in use. To the above ends, the present invention consists in the bobbin hereinafter described and particularly defined in the claims.

In the accompanyingdrawings illustrat- W ing the preferred form of the invention, Fig. 1 1s a longitudinal, sectional elevation of the bobbin; and Fig. 2 is a detail hereinafter referred to. The illustrated embodiment of the invention described as follows: The body the-bobbin 1 isprovided with a blade 2wand a butt 3. The butt of the'bobbin has an. enlarged end. It receives the reinforcing ringed, sprung into grooves formed. in the, exterior surfacei of the butt of the bobbin, These reinforcingrings i serve not ohly as devices to strengthen the butt of the bobbin, and to prevent splitting, butthey also serve as the holdingmeans by which the bobbin Lils held in the shuttle of a weft replenishing 00m. The butt of the bobbin is provided with a concentric recess or spindle hole which is reinforced with a ferrule 5, shown in side elevation in Fig. 2. This ferrule is cylin drical in form throughout the principal portion of its length, and fits insidethe butt recess 6 of the bobbin. Near the inner end of the body of the ferrule it is provided with an expanded portion or rounded or filleted enlargement 7,, which,as shown, is located close to but short of theend of the ferrule;' The bobbin butt isfprovided with an annular recess 8, which is located at such a distance from the-end of the bobbin as to be adapted to receive the enlargement 7. of the ferrule when the latter is forced into the hole in the end of the bobbin. It is to be observed that the enlargement 7 is intermediate the ends of the body of the ferrule, and that-in inserting the ferrule in the' bobbin this'enlargement of the ferrule is pressed into ahdle in the wood somewhat smaller than the size of the enlargement. The wood of the bobbin at the time it is re ceiving this ferrule is in such a condition that it will withstand the compression incident to the passage of the enlargement by it, and will more or less close inon the body of the ferrule after the "enlargement has passed. This enlargement is received in the 17, 1925. Serial 1101 c9312.

annulanrecess 8, and variations from accupositioning of the recess 8 in the bobbin 1 rate with respect to the enlargement on the ferrule may occur W.thoutimpairing substantially the holding quality of the enlargement by engagement'with" the recess. This tain a uniform diameter of hole so that they f will position themselves correctly onthe 0 spindle of the spinning frame.

The,outer end of the ferrule body is provided. with a flange 9, which extends out wardly and then bends back parallel to the body of the ferrule-at a distance therefrom. This concentric circular inturned edge 'of the ferrule flange, as it may be called, is provided with teeth or irregularities, which, when he ferrule is inserted in the bobbin, indent themselves into the end of the body of the bobbin, so as to secure a firm hold on the wood of thereof and acting thereby to prevent the ferrule from rotating in the shuttle body.

The ferrules are made of the form shown in Fig. 2. The bobbins are made of the form shown .in Fig. 1, with the annular recess'8 formed therein, but Without any recess to receive the back-turned, or inturned serrated edge of the ferrule flange which, under th rule into theQbobbimJndents itself intothe end of the bobbin.

The forcing of the enlargement of the .ferrule body throu h the smaller opening in the end of the bob hin butt subjects the wood to a strain which, in some instances, would subjected to repeated handling will still rethe bobbin by the deformation e pressure exerted in forcingf'the ferbe suflicient to crack it, but in the manufac ture off-bobbins of this construction, the bobbin is embraced and tightly held by a gripping device so as'to prevent any expansion of the bobbin butt: by the pressure exerted on the inside thereof by the enlargementpn the body of the ferrule.

While the present invention isillustrated as embodied in a bobbin for use in a'weft' replenishing loom, it isto be understood that the invention may befemployed in any form of bbbbinprovided with a. central opening which it is desired to reinforce, or in the manufacture of spools, or. other thingshaving acentral opening whichis reinforced-5 the claims, therefore, are to be read and understood' in the light of this statement, as embracing any article of manufacture made of soft material such as wood, which is provided with a hole and reinforced by a ferrule having the features of construction defined in the claims. p

Having thus described the invention, what is claimed is:

1. A bobbin for weft replenishing looms having a Wooden body portion consisting of a blade and an enlarged butt provided with a concentric spindle-hole, reinforcing rings on the exterior of the butt of the bobbin, and a reinforcing ferrule on the interior of the butt of the bobbin, provided with an annular filleted enlargement near but short of its inner end, the hole in said bobbin butt being provided with a recess to receive said enlargement, and said ferrule being also provided with an outwardly extended flange having a backwardly extended, irregularly formed edge adapted to penetrate the end of the bobbin and hold the ferrule from rotation with respect thereto by deformation of the wood bythe backwardly extended edge. 2. A bobbin having a butt of comparatively soft material, provided with a hole in its end, an outwardly. flanged reinforcingi metallic ferrule ,provided 'in ermediate ts ends with an annular filleted enlargement on its body, said hole in the bobbin being provided with an annular recess to receive such enlargement, and cooperating projections and recesses on' the bobbin and ferrule to holdthe ferrule from rotation with respect to the bobbin.

3. A bobbin having a body portion of comparatively yielding material, having an exterior strengthening reinforcement, and an interior strengthening reinforcement, consisting of a ferrule having an enlargement on the body thereof, said hole in the article being provide'd with. an annular recess to receive the enlargeinenton the body of the ferrule, said ferrule being provided with an outwardly extended flange "havingm backwardly turned concentric circular lip adapted to be forced into the end of the body of the article to hold the ferrule and article from rotation with respect to each other.

In testimony whereof I have signed my name to "this specification.
